Liquefaction site pile foundation composite stress mechanism simulation device and test method thereof
The invention discloses a liquefaction site pile foundation composite stress mechanism simulation device and a test method thereof and belongs to the technical field of rock-soil earthquake engineering. An upper end of a vertical loading device is in sliding connection with an upper cross beam of the reaction frame, a lower end of the vertical loading device is connected with an upper end face of the steel outer sleeve, a pile cap is fixed in the steel outer sleeve, a pile body is embedded into the laminated shear model box, and the bottom of the laminated shear model box is fixed to the saturated soil liquefaction excitation device; the horizontal cyclic loading device is in sliding connection with a vertical beam corresponding to the reaction frame, the horizontal cyclic loading device is connected with a pile cap through a steel jacket, and the model box loading device is in sliding connection with a vertical beam corresponding to the reaction frame; when the model box loading device works, the model box loading device is detachably connected with a frame body corresponding to the laminated shear model box, and the vertical loading device, the horizontal cyclic loading device, the model box loading device and the saturated soil liquefaction excitation device are connected with a computer through data lines. The device is used for simulating the composite stress mechanism of the pile foundation of the liquefaction site.
